textproc/zet: update to 0.2.5

[0.2.5] - 2022-11-10
Changed
 - Bump Minimum Supported Rust Version to 1.64.0
 - Switch from failure to anyhow
 - Performance enhancements:
     - Use Cow keys for UnionSet and CountedSet so we can borrow the lines of
       the first file rather than allocating them
     - If line is in a CountedSet, don't allocate a key
     - Use FxHash — averages 10-15% faster on large files
     - Convert Diff and Union to use CowSet
     - Convert Single, Multiple, and Intersect to by-line algorithms
     - No longer create map/set for args after the 1st
 - Refactor and expand internal documentation.
 - Change Single/Multiple code to use a single NonZeroUsize operand ID rather
   than two u32 IDs
